[12] The Hummer EV is offered in two variants: a pickup truck and a sport utility vehicle (SUV), unveiled in October 2020 and April 2021 respectively.

[13] Weighing roughly 10,000 pounds (4,500 kg), the Hummer EV is among the heaviest consumer automobiles currently sold in the United States.

[14] Its size, mass, and acceleration have led to concerns about the danger it poses to other road users in the event of collisions, as well as its efficiency and environmental impact.

[19] With a gross vehicle weight rating of 10,400 pounds (4,700 kg), it is classified as a class 3 medium-duty truck in the United States.

[25] Edition 1 has three electric motors with 1,000 hp (750 kW; 1,000 PS), 329 miles (529 km) of range,[9] and is fitted with the Extreme Off-Road package, which includes 35-inch (890 mm) mud-terrain tires, skid plates, and rock sliders.

The "Crab Walk" feature, which allows the Hummer EV to travel diagonally by using four-wheel steering, comes standard with Edition 1.

Edition 1 also includes UltraVision underbody cameras for easier off-road maneuverability and visibility, adaptive air suspension, steel underbody armor, a system called "Extract Mode" which lifts the suspension six inches (150 mm) for more clearance, a driver assistance system that allows for automatic lane change and hands-free driving on compatible highways that have been mapped by GM, a digital key, removable roof panels, and GMC's MultiPro Tailgate.

[31] This was set to be the base Hummer EV trim which was to include super cruise, HD surround view, digital key, infinity roof, a multi pro tailgate, and rear drop glass among other standard features.

[35] On January 30, 2020, GM released three advertisements for the Hummer EV, followed by Super Bowl LIV commercials on February 2, 2020, with LeBron James as the spokesperson.

[19][42][43][22] Jennifer Homendy, the head of the United States' National Transportation Safety Board, said that the Hummer EV is an example of a heavy electric vehicle, which is more likely to kill or seriously injure other road users in the event of a collision, alongside products from other manufacturers such as Ford or Volvo.

[21][23] General Motors responded to concerns by saying that their "customer's safety is a top priority regardless of the type of propulsion or mass of the vehicle".

[43][49] It is intended to appeal to customers who otherwise would not have considered buying an electric vehicle, with it expected that most owners will purchase it as a second or third car, likely negating[how?]
